4 Claims.

The present invention relates to improvements in shoe-heel construction.

An object of the invention is the provision of a shoe heel of exceptional durability.

Another object of the invention is the provision of a heel assembled Vand fastened to the shoe in such manner as to obviate uncomfortable projections.

A further object ofthe invention is the provision of a heel of the aboveV character which is very securely fastened to the shoe.

Still another objectof the invention is the provision of a shoe heel in which the component lifts are fastened together and to the shoe entirely by stitching.

A still further object of the invention is the provision of a shoe heel of the .aforesaid char-r acter which may be quickly and easily assembled and attached to a shoe.

Other objects and advantages of the invention will become apparent asY the description progresses.

In the accompanying drawing forming a part of this specification and in which like deference characters are employed to designate corresponding parts throughout the samer Figure 1 is a fragmentary perspective view showing the improved heel associated with a shoe outsole and Welt,

Figure 2 is a similar view showing the filler strip in detached relation,

Figure 3 is a transverse section through the inner section of the heel,

Figure 4 i's a similar View showing the manner of cutting a groove therein, y

Figure 5 is a similar view showing the heel attached to an outer section, l

Figure 6 is a transverse section taken on the line 6-6 of Figure 1 showing the complete heel assembly, and

Figure 7 is a fragmentary sectional view showing the heel associated with an outsole, welt, insole and upper of a shoe. t

Referring to the drawing, wherein for the purpose of illustration is shown a preferred embodiment of the invention, O generally designates the heel portion of a conventional shoe outsole having positioned on the marginal portion thereof a welt strip W as is well-known in the art.

In the'formation and assembly of the heel a pair of lifts I0 and II are arranged in face to face layers beneath the heel portion of the outsole O, as shown at Figure 3, and stitched to the said outsole and welt W by a row of stitching I2 assuming an rangular position. The next step in the formation of the heel resides in cutting, in the side edges and rear of the assembled section S thus formed, a continuous angular reentrant groove I4 preferably dening an inclined side Wall which provides, as shown at Figures 4 and 5, an approximately triangular shaped channel formed with an arcuate, rela-y tively small in-cut groove I5 at the base, adapted to provide clearance for a stitching machine. This groove is shaped to form a ledge projection I6 at the edge of the lift II and may actually constitute cutting away a triangular shaped portion of the outsole O and the upper lift II)y and to expose a marginal portion of the top surface of the lift I I.

The next operation consists in disposing a plurality of lifts, as for instance, the'intermediate lift I8 and the top lift I9, in face to face laminated arrangement below the lift II of the inner section S and stitching the same to the projecting ledge IB by vertically disposed stitching 20. Thus, the lower lifts I8 and I9 constitute an outer section S rmly secured by the stitching 2u to the inner section Si.

Following assembly of the two heel sections a t filler strip 22, of triangular cross section, is fitted in and secured, by suitable adhesive, within the angular groove I4. The relatively small in-cut groove I5 is filled by the adhesive, as indicated at 23.

'I he component elements of the heel, including the lifts and filler strip, are preferably formed of leather.. Furthermore, the lifts of the respective sections and the assembled sections are secured together by stitching and the complete heel assembly is likewise secured to the upper and welt strip by stitching so that nails or like fasteningr elements are completely eliminated and the'discomfort often resulting therefrom is obviated.

It is to be understood that the form of my rinvention herein shown and described is to be 1. A shoe heelof the character described comy prising an upper section including a plurality of lifts arranged in face to face relation secured together and to shoe sole by stitching, the said section having a groove formed therein; and a lower section including a plurality of lifts se- 3. A shoe heel of the character described com-r pn'sing an upper section composed of a pair of lifts secured by stitching to a shoe sole, the edge portion of the said sole and upper lift being cut away to form an angular re-entrant groove ex- 400,282- cured togetherand to the said upper section by,

posing a top marginal portion of the lowerniost lift of the section; a bottom section composed of a pair of lifts secured together and to the marginal portion of the lowermost lift of the upper section by stitching; and a ller strip secured by adhesive in the said groove.

4. In a shoe having a welt, a shoe heel comprising at least four lifts stitched together and to the welt, said heel including more than two lifts stitched together and to `the Welt at an in- Ward angle, the ylifts stitched to the"we1t being tapered inwardly to forni' an' angular groove, more than two lifts stitched to the previously disclosed lifts outwardly of the welt-lifts stitches, and a lller strip secured within the groove.
